Interior drain tile, sump basins, and vapor barrier wall systems installed by technicians who've done this hundreds of times in Corunna, MI basements.
Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.
Every technician carries full state licensing and liability coverage before they ever step into your basement.
Most inspection requests get a same-day or next-day appointment, not a two-week wait.
You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.
Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.
Every Corunna, MI Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.
Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.
The cove joint where the floor meets the foundation wall is one of the most common Corunna, MI leak points, and we seal it as part of every interior system.
We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.
Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.
A quick phone conversation lets us bring the right equipment on the first visit instead of a second trip.
We also check exterior grading and downspouts, since a lot of basement leaks start outside, not inside.
We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.
Most residential basement jobs finish in one to three days, and we test the sump pump under load before we leave.

— Corunna Customer

Cost depends on linear footage, sump basin size, and whether cove joint sealing is included — we won't give a number without an in-person inspection.
Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

Not always — an isolated, non-leaking crack can sometimes be handled with injection alone.
We provide photos and moisture readings that many Corunna, MI homeowners have used to support a claim.
Yes, every interior drain tile and sump installation comes with a written warranty, explained in full before you approve the quote.
